Nvidia preparing GTX 680M for Computex

According to a post over at Videocardz.com, it appears that Nvidia is preparing a new Kepler-based mobile chip. It will be based on the GK104 GPU and will be known as the GTX 680M. According to early performance figures, the GTX 680M will not be able to dethrone AMD's current mobile flagship, the HD 7970M.

Although precise clocks are still missing, the early specs for the GTX 680M suggest that we are looking at a GK104-based chip that will have either 744 or 768 CUDA cores and feature up to 4GB of GDDR5 memory paired up with a 256-bit memory interface. The rumoured TDP of this chip is up to 100W.

The leaked benchmarks shows that the card could end up around 37 percent faster than current Nvidia flagship, the GTX 670M, which is based on Fermi architecture. It scores 4905 points in 3DMark 11 performance preset when paired up with Core i7-3720QM Ivy Bridge CPU.

As noted, the 4905 score, if proven to be accurate, is not enough to dethrone AMD's current flagship, the HD 7970M. According to previous benchmarks of the HD 7970M, it scores 6125 points in the same 3DMark 11 when paired up with Intel's Core i7-2820.

Of course, we are still looking at early reports and rumours, but it is nice to know that Nvidia is at least considering such a chip and we are surelly looking forward to see some more details at Computex event when it kicks of on June 5th.
